Step-by-step explanation:
1) The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length....
= Solution ,
Length ( L ) = ?
breadth ( b ) = 10xy cm
area ( a ) = ( 30x² + 20xy )
Now ,
area ( a ) = l × b
or, ( 30x²y + 20xy ) = L × 10xy cm
2) Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
= Solution,
The product of 3x and 4y = 6xy
= 6x - 4xy

An inequality may be used to model the given situation. The phrase, "no more than" implies "less than or equal to". Therefore, the inequality is:
15 ≤ t / 5
Solving the inequality of t, we get:
t ≥ 75
This means that the number t is at least 75 (the phrase at least implies greater than or equal to)
Hope this helps!
Confidence intervals and hypothesis testing share the characteristic that they are both inferential techniques
